MODEL 1152 PLL

Model 1152-A Phase Locked Oscillator

Designed to replace crystal oscillator LO chains for microwave receivers and transmitters used by Amateur Radio operators. Now there is an inexpensive alternative to those unstable high frequency crystal oscillators which drift constantly, allowing precise receiver/transmitter frequency settings using a stable external 10 MHz or 100 MHz reference oscillator like a TCXO, Oven Controlled Oscillator or a Rubidium Oscillator. One of the frequency options allows the Model 1152-A to be used as a Microwave Beacon driver source between 1296.8 MHz to 1297 MHz.

The Model 1152-A outputs one of 8 selectable frequencies listed in Table 1 and Table 2.

Table 1 - Model 1152-A Frequency Options

Frequency Option	Frequency Band	IF Frequency
1152 MHz	1296 MHz	144 MHz
1268 MHz	1296 MHz	28 MHz
1296.8 MHz	1296 MHz	Beacon Source

Using external frequency multipliers, the Model 1152 base frequencies will provide local oscillator power for the following microwave bands, with the corresponding receive/transmit IF frequencies shown in Table 2.

Table 2 - Multiplier Frequency Options

Frequency Option	Multiplier	Frequency Band	IF Frequency
1080 MHz	X2	2304 MHz	144 MHz
1128 MHz	X2	2400 MHz	144 MHz
1104 MHz	X3	3456 MHz	144 MHz
1123.2 MHz	X5	5760 MHz	144 MHz
1136 MHz	X9	10,368 MHz	144 MHz
1104 MHz	X9	10,368 MHz	432 MHz

NOTE: Custom frequencies are available on special order. Consult JWM Engineering Group, Inc. for information and pricing.
